Yea... there should be. But I'm not versed enough yet to distinguish a healthy log from a faulty one.
At least I don't see any big striking errors in there.

I'll redownload the blockchain (copied over the one from 0.6.6.0 before) and see if I've more luck then.

edit: Okay 9/10 accepted after 14 hours now. Given that on average I should find a block every 1.4 hours with my hashrate of 1150 kH/s I think that's okay.
